ROTARY SAN u-Pu M SPECIFICATION forming part of Letters Patent No. 610,992, dated September so, 1898.

Application filed March 10, 1898. Serial No. 673,324. (No model.)

T0 Cl/ZZ whom it may concern.-

Be it known that 1, JOHN MANN, a citizen of the United States, residing at Butte City, county of Glenn, State of California, have invented an Improvement in Rotary Sand- Pumps; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus which is especially designed for raising sand, gravel, &c., where there is too much water to be handled otherwise.

It consists, essentially, of an irregular oval casing formed of sections of steel andiron,having a shaft extending transversely through it, and a piston formed by a peculiar arrangement of fixed and hinged plates which are adapted to travel within the casing when the shaft is revolved, so as to raise the material through an inlet-opening and discharge it upon the opposite side through an outlet.

Theinvention also comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a vertical section on the line m at of Fig. 2. Fig. 2 is a vertical section on the line y y of Fig. 1.

The casing is composed of sides A and B and a rim 0, having inner faces made of steel to resist wear. At the bottom of the casin g is an inlet-opening D, and at the top, or essentially opposite to the inlet-opening, is a discharge opening E. Through this casing passes a shaft F, suitably journaled and having upon its outer end a pulley G or other means for applying power to rotate it. This shaft has fixed to it metallic plates I in such a manner that they are tangent to a circle somewhat larger than the shaft to which they are fixed. These plates extend outwardly at right angles with each other, are bent as shown at '6, thence extending at right angles with the former direction and parallel with the part I of the next adjacent plate upon that side, as shown at I. At the ends the parts I are turned into a hook shape (shown at I) and adapted to engage the ends of the pistonplates J, which are bent, as shown at J, so that the other arm Jiextends inwardly between the parts I and I, each two adjacent plates moving essentially close to the parts I.

outer ends extend to about the same length,

K K are flat plates which lie closely against the parts I of the first-named plates, and the lying between the parts J of the piston-plates and the part I. The inner ends of these plates K are bent into hook form, as shown at k, and these hooks engage with corresponding hooks L, which are secured to the shaft, the plates of which they are composed extending a short distance outward from the shaft, lying close against the inner surfaces of the plates I, and being bent in reverse curve, so as to be engaged by the hooks of the plates K.

The operation of the device will then be as follows: When the shaft is rotated, the angleplates J, turning loosely at the outer ends, where they engage with the turned-over ends of the plates I, will drop upon the rim of the casing, the casing standing vertically, as shown, so that the suction-pipe is downward. These plates move over the lower part of the casing, acting as suction-pistons to draw in the sand through the inlet and to discharge it at the outlet-passage at the opposite side, the plates dropping in toward the center as they pass toward the top of the apparatus.

Openings are made in the curved ends of the arms I to let out any sand and water that get in at these joints.

The whole device is easily kept in order and serves as an eflicient means for raising sand or gravel which is mixed with water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A sand-pump comprising an irregularly oval casing, a shaft extending through the sides of said casing having arms fixed to it and extending out tangentially, thence being bent at right angles and having hook=shaped ends form ed upon them, in combination, with angular plates, one end of each of which engages one of the hook-shaped ends of the axle-plates and the angles of said pistonplates adapted to travel in contact with the inner periphery of the rim of the casing.

A sand-pumping apparatus consisting of a casing in the form of an irregular oval having inlet and discharge passages at approximately opposite sides, a shaft extending through the sides of the casing journaled and having means by which it is rotated, plates tion of the axle-plates, the interior ends of fixed tangentially to the shaft extending outsaid plates being bent over into hook form ward, thence bent at right angles parallel and engaging with bent hook-shaped plates with the body of the next adjacent plate havhaving the inner ends fixed to the axle inte- I 5 5 ing the outer ends turned into a hook-shaped rior to the first-named plates.
